Syllabus

1. Course Number: TED 226 Course Name: Application and Processing of Engineering Materials

Credits: 3 Prerequisite: None 2. Instructor: Dr. Larry Horath or any qualified TED faculty member 3. Rationale for the Course:

Students are required to develop technological literacy, especially those aspiring to become technology education teachers. This course addresses the needed skills and competencies and serves as an introduction to metallic, ceramic, and plastic materials including the selection, preparation, conditioning, forming, shaping, and finishing of these materials. There will be approximately two lecture hours and four laboratory hours per week which allow students to explore facets of materials science, selection, processing, and testing. This course will further serve as the skills foundation for other laboratory courses that require the processing of materials.

4. Objectives:

Upon successful completion of this course the student will be able to

a. Describe primary and secondary methods of processing common industrial materials.

b. Identify and differentiate between different industrial materials.

c. Define, describe and evaluate different physical, mechanical, chemical, thermal, electrical, and other common properties.

d. Analyze various properties through accepted, standardized tests.

e. Use permanent and consumable molds to produce castings. f. Identify the various molding and casting techniques along with their advantages, disadvantages, and applications. g. Change the shape of metallic, ceramic, and plastic materials

using a variety of techniques including cold and hot forming, extruding, blow molding, calendering, and mechanical forming.

h. Perform common lathe and milling operations to shape materials. i. Identify and properly apply various mechanical fasteners. j. Apply electric arc welding, oxy-acetylene welding, brazing, and

soldering processes in joining similar and dissimilar materials. k. Perform drilling, sawing, tapping, grinding, sanding, and

similar common industrial processes. l. Cut, trim, and shape metallic materials using a variety of techniques such as flame cutting,

shearing, and assorted hand tools. m. Heat treat metals using annealing, normalizing, hardening, tempering, and work hardening. n. Chemically condition plastic materials using catalytic action and polymerization.

o. Assemble various materials using mechanical fasteners, adhesives, and cohesive processes. p. Apply suitable surface finish preparation techniques, correctly select a proper finish, and properly

apply the finish for a variety of materials.

5. Proposed Catalog Description:

This course is designed to serve as an introduction to metallic, ceramic, and plastic materials including the selection, preparation, conditioning, forming, shaping, and finishing of these materials. There will be approximately two lecture hours and four laboratory hours per week. These activities allow students to explore the many facets of materials science, selection, processing, and testing. Additionally, this course serves as the foundation for other laboratory courses that require the processing of materials.
